It was invented by the Scottish inventor Andrew Gordon, Professor of Natural Philosophy at the University of Erfurt, Germany.[ citation needed] About 1742 he invented a device known as the "electric chimes", which was widely described in textbooks of electricity. Franklin made use of Gordon's idea by connecting one bell to his pointed lightning rod, attached to a chimney, and a second bell to the ground.
My article
Scientific investigation on of the phenomena of lightning originates with Benjamin Franklin. He accumulated analogical evidence favoring the supposition that lightning must be an electrical discharge on a large scale. [1] This device is named for Benjamin Franklin, an early adopter who used it during his experimentation with electricity. [2] In his collection of essays, Benjamin Franklin wrote: ‘‘In September 1752 I erected an Iron Rod to draw the Lightning down into my House, in order to make some Experiments on it, with two Bells to give Notice when the Rod should be electrified. A Contrivance obvious to every Electrician." [3] He adapted a setup made in 1742 by German professor, Andrew Gordon. Franklin’s Bells was an early demonstration of converting static electrical energy into continuous mechanical motion. [4]
The bells consist of a metal stand with a crossbar, from which hang three bells. The outer two bells hang from conductive metal chains, while the central bell hangs from a nonconductive thread. In the spaces between these bells hang two metal clappers, small pendulums, on nonconductive threads. A short metal chain hangs from the central bell.
The central bell's chain is put in contact with the inner surface of a Leyden jar, while the outside surface of the jar is put in contact with the metal stand. Thus, the central bell takes its charge from the inner surface of the jar, while the outer surface charges the two bells on the conductive chains. This causes the bells to have a difference in electrical potential equal to that between the inner and outer surfaces of the jar. The hanging metal clappers will be attracted to one bell, will touch it, pick up its charge, and be repelled; they will then swing across to the other bell, and do the same there. Each time the clappers touch a bell, charge is transferred between the inner and outer surfaces of the Leyden jar. When the jar is completely discharged, the bells will stop ringing.

Edited to correct grammar and punctuation.
The Franklin's Bells are an example of an electrostatic motor, working on the principles of attraction and repulsion of electromagnetic fields and charges. This development was so substantial at the time that Benjamin Franklin would adopted his own version of the "German chimes" in further experimentation into the odd world of electricity. Franklin would go on to compile his experiments and bring his new lightning rod and the Gordon bells together.
I did not get any feedback but I will continue to add additional sources. I need to have more variety in the texts I choose, even though few texts are available. I also plan to improve the conciseness of my thoughts and try not to fluff.
